Plasma panel comprising cement partition barriers

Abstract

Display panel comprising two plates leaving between them a sealed space that is filled with a discharge gas and is partitioned into discharge cells bounded between these plates by barrier ribs made of a mineral material comprising a mineral binder based on a hydraulic binder, and a mineral filler. By using a hydraulic binder instead of a glassy mineral binder, the display panels may be manufactured at lower temperature.

1. A plasma display panel comprising two plates having a sealed space between the two plates that is filled with a discharge gas, wherein the sealed space is partitioned into discharge cells bounded between the two plates by barrier ribs made of a mineral material comprising a mineral filler and a mineral binder, which aggregates said mineral filler, wherein said mineral binder is a hydraulic binder which is in the hydrated state so as to aggregate said mineral filler. 
   
   
     2. The display panel as claimed in  claim 1 , wherein said hydraulic binder is a cement. 
   
   
     3. The display panel as claimed in  claim 2 , wherein said cement is based on aluminates or aluminosilicates. 
   
   
     4. The display panel as claimed in  claim 1 , wherein the proportion by weight of mineral filler in said mineral material is equal to or greater than 50%. 
   
   
     5. The display panel as claimed in  claim 1 , wherein the mineral filler comprises more than 50% by weight of silica and/or alumina. 
   
   
     6. The display panel as claimed in  claim 1 , wherein the porosity of said barrier ribs is equal to or greater than 15%. 
   
   
     7. The display panel as claimed in  claim 6 , wherein the porosity of said barrier ribs is greater than 25%.
